At least one Australian remains unaccounted for after the Barcelona terror attack, Foreign Minister Julie Bishop says, as the injury toll continues to climb.
Four Australians were among the almost 100 people injured when a van plowed through civilians in the popular tourist spot Las Ramblas, in Barcelona.
One Australian is unaccounted for, Bishop told reporters, while three others required consular assistance.
A NSW woman is in a serious condition in hospital while another woman, also from NSW, was seriously injured but is now in a stable condition, the foreign minister said.
Bishop said she understood two men from Victoria were hit by the car and injured, and both have since been discharged from hospital. Australia was liaising with authorities to find the Australian who is unaccounted for.
"The situation is evolving," Bishop said.
"We are concerned, but we are working closely with authorities to determine the whereabouts of the one Australian unaccounted for."
There is no indication any Australians were involved in terror incidents in nearby Cambrils and Alcanar.
"We understand that the terrorist organisation, ISIS, has claimed responsibility," Bishop told reporters.
"We condemn in the strongest possible terms these brutal and cowardly attacks, and in the case of Las Ramblas clearly designed to harm and affect tourists who were visiting the area.
The Australian Government remains committed to ensuring that Australians are as safe as they can be, either overseas or here in Australia."
Australians in the area have been advised to ensure that they stay in their hotels and follow any directions given by local authorities.
The Department of Foreign Affairs and Trade (DFAT) has said that Australians concerned about family or friends in the region should contact them directly before calling the 24-hour Consular Emergency Centre on 1 300 555 135 (+61 2 6261 3305 if calling from overseas).Suggest a correction
